Earthquakes

A year-and-a-half since a 7.2 magnitude earthquake destroyed parts of Mexicali on Mexico's northern border, the U.S. and Mexico will join efforts in earthquake research and preparedness.

Engineers know a lot about how earthquakes shake and stress modern buildings, and much of that knowledge has already been incorporated into California's building codes to help save lives.

Federal Defense and Homeland Security funding has poured into San Diego since 9/11. KPBS Reporter Alison St John looks at how that money has benefited the region.

Nuclear Facility Also A 'Hardened, Secure Site'

San Diegans will remember October 2007, when half a million people were evacuated during the devastating Witch Fire. We'll talk about what goes into a decision to evacuate, what are the downsides of a mass evacuation and what we should all have in our emergency kits at home.

When we send our children to school, we want to know they're safe, which is why it's worth paying attention to whether school buildings are ready for a possible earthquake.

Researchers from the Scripps Institution of Oceanography say diverting the Colorado River 100 years ago may have re-set the earthquake clock. We'll hear how the lack of "lake load" on the Salton Sea plays a role in the timing of large earthquakes on the southern part of the San Andreas fault.

How are residents in Mexicali and the Imperial County still being affected by the 7.2 magnitude Easter earthquake that struck one year ago? And, what are some of the unique things geologists have learned about the temblor over the last year? We'll look back on how the earthquake impacted our region, and discuss how the knowledge we've gained could influence theories about quake mechanics in the future.

A year ago, a 7.2 magnitude earthquake shook the region from Mexicali as far north as Los Angeles. Around the epicenter, in the Mexcali Valley, about 30 miles south of the border, the quake left 25,000 homeless and ruptured lives. People are slowly putting things back together.

Delays in chip production could mean longer waits for the new iPad and fewer deals on other hot items.
